Airworthiness Directives; The Boeing 

Company Model 777–200 and –300 

Series Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 777–200 

and –300 series airplanes. This 

proposed AD would require replacing 

certain single-tabbed bonding brackets 

in the airplane empennage with twotabbed bonding brackets. This proposed 

AD would also require, for certain 

airplanes, installing new bonding 

jumpers, and measuring the resistance 

of the modified installation to verify 

resistance is within specified limits. 

This proposed AD was prompted by 

reports of two failures of the singletabbed bracket on the rudder. We are 

proposing this AD to prevent failure of 

the bonding jumper bracket, which 

could result in loss of lightning 

protection ground path, which could 

lead to increased lightning-induced 

currents and subsequent damage to 

composite structures, hydraulic tubes, 

and actuator control electronics. In the 

event of a lightning strike, loss of 

lightning ground protection could result 

in the loss of control of the airplane. 

DATES: We must receive comments on 

this proposed AD by December 19, 

2011.

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposal. Send your comments to 

an address listed under the ADDRESSES

section. Include ‘‘Docket No. FAA– 

2011–1165; Directorate Identifier 2011– 

NM–002–AD’’ at the beginning of your 

comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the 

closing date and may amend this 

proposed AD because of those 

comments. 

We will post all comments we 

receive, without change, to http:// 

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this proposed AD. 

Discussion 

We received reports of two failures of 

the single-tabbed bracket on the rudder. 

The bracket was discolored and melted, 

the tab was completely severed and 

burned, and the bonding jumpers were 

detached from the bracket. We also 

received a report of a similar failure of 

the ground clip that connects to the 

other end of the jumpers to the vertical 

stabilizer. Boeing has determined that 

the root cause of these failures was a 

combination of electromagnetic forces 

on the jumpers and resistive heating of 

the bracket and ground clip during 

lightning strikes. This condition, if not 

corrected, could result in loss of 

lightning protection ground path, which 

could lead to increased lightninginduced currents and could 

subsequently damage composite 

structures, hydraulic tubes, and actuator 

control electronics. In the event of a 

lightning strike, loss of lightning ground 

protection could result in loss of control 

of the airplane. 

Relevant Service Information 

We reviewed Boeing Service Bulletin 

777–55A0014, Revision 1, dated April 1, 

2010. This service bulletin describes 

procedures for replacing certain singletabbed bonding brackets in the airplane 

empennage with two-tabbed bonding 

brackets. 

Boeing Service Bulletin 777– 

55A0014, Revision 1, dated April 1, 

2010, specifies prior or concurrent 

accomplishment of Boeing Service 

Bulletin 777–55A0010, Revision 1, 

dated April 17, 2001, for installing new 

bonding jumpers, and measuring the 

resistance of the modified installation to 

verify resistance is within specified 

limits.

Federal Register / Vol. 76, No. 214 / Friday, November 4, 2011 / Proposed Rules 68367 

FAA’s Determination 

We are proposing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

develop in other products of these same 

type designs. 

Proposed AD Requirements 

This proposed AD would require 

accomplishing the actions specified in 

the service information described 

previously. 

Costs of Compliance 

We estimate that this proposed AD 

affects 87 airplanes of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Replacement ........................................................... 21 work-hours × $85 per hour = $1,785 ................ $1,235 $3,020 $262,740 

ESTIMATED COSTS FOR CONCURRENT ACTIONS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Replacement ........................................................... 66 work-hours × $85 per hour = $5,610 ................ $2,668 $8,278 $248,340 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

section 106, describes the authority of 

the FAA Administrator. Subtitle VII: 

Aviation Programs, describes in more 

detail the scope of the Agency’s 

authority. 

We are issuing this rulemaking under 

the authority described in Subtitle VII, 

Part A, Subpart III, Section 44701: 

‘‘General requirements.’’ Under that 

section, Congress charges the FAA with 

promoting safe flight of civil aircraft in 

air commerce by prescribing regulations 

for practices, methods, and procedures 

the Administrator finds necessary for 

safety in air commerce. This regulation 

is within the scope of that authority 

because it addresses an unsafe condition 

that is likely to exist or develop on 

products identified in this rulemaking 

action. 

Regulatory Findings 

We determined that this proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would not have a 

substantial direct effect on the States, on 

the relationship between the national 

Government and the States, or on the 

distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify this proposed regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Is not a ‘‘significant rule’’ under 

the DOT Regulatory Policies and 

Procedures (44 FR 11034, February 26, 

1979), 

(3) Will not affect intrastate aviation 

in Alaska, and 

(4) Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.

Airworthiness Directives; DASSAULT 

AVIATION Model MYSTERE-FALCON 

900 Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

DASSAULT AVIATION Model 

MYSTERE-FALCON 900 airplanes. This 

proposed AD results from mandatory 

continuing airworthiness information 

(MCAI) originated by an aviation 

authority of another country to identify 

and correct an unsafe condition on an 

aviation product. The MCAI describes 

the unsafe condition as: 

Several Mystere-Falcon 900 aeroplanes 

experienced fuel leakage from a defective 

fuel high-level sensor located in the wing 

front spar. 

Investigations revealed that the leakage 

was due to a defective fuel quantity sensor 

* * *. 

This condition, if not detected and 

corrected, could lead to an internal fuel 

leakage with significant fuel vapours, which 

could result in a fire hazard. 

* * * * * 

The proposed AD would require 

actions that are intended to address the 

unsafe condition described in the MCAI. 

DATES: We must receive comments on 

this proposed AD by December 19, 

2011.
